Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net

Everytime I build my site in VS2010 Beta I recieve a few ajax errors before the site loads here they are in order as they pop out on the build; 


throw new Error("AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the AjaxScriptManager in System.Web.Ajax.dll, or use the ToolkitScriptManager in AjaxControlToolkit.dll.");


And then Next this line is throwing an error, I have a watermark ajax field on the page that I created a long while ago;

Sys.registerComponent(Sys.Extended.UI.TextBoxWatermarkBehavior, { name: "watermark", parameters: [{name:"WatermarkText",type:"String"}, {name:"WatermarkCssClass",type:"String"}] });

Using ToolkitScriptManager, but still receiving "AjaxControlToolkit requires ASP.NET Ajax 4.0 script


I've read all the posts with this same issue and have not been able to resolve it in my case.  Is the wrong version of the Toolkit being cached somewhere?
I upgraded my web application from 3.5 to 4.0 and am getting "AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced." on pages that are using ToolkitScriptManager, not ScriptManager.
For example

Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels
.Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls
The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

Need help, ASP.NET AJAX, AjaxControlToolkit


Hi, please forgive me if this question already answered before. I need help urgently.

I'm developing a web application (not website) which can be created under "New->Project->ASP.NET Web Application". I'm using Visual Studio 2010.

My problem is, all AJAX working fine except for the AjaxControlToolkit. I try to include the ValidatorCalloutExtender and it failed to work as in it won't display. However I created same thing using "New->Website->ASP.NET Website" instead and it works.

Question: Is AjaxControlToolkit only work on website but not web application? Is there anyway to use it on web application?

Using tabs from the AjaxControlToolkit causes error: ...control contains code blocks (i.e. <% ... %>


I'm getting the error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

When attempting to add the tabs from the AjaxControlToolkit.  A little background..Theres an existing aspx page in a microsite which used the accordion control and the tabbed control ...I need to modify this page to use a different masterpage. 

The original site was .Net Framework 2.0 and the page in question used AjaxControlToolkit 1.0. which I manually installed originally.  Some of the site has been further developed using the .Net Framework 3.5.  (Come with AjaxControlToolkit) Now I have come to update this aspx page and I get the error above.

I have narrowed the down to the TabContainer (I think)  Does anyone have any experience with this sort of problem?  Also what version of the AjaxControlToolkit should be with the .Net Framework 3.5? I have 1.0.20229.20821. 

I also tried to browse to the AjaxControlToolkit.dll to add the tools to the tool box as they're missing... thinking this may be an indicator as to why it wasn't working. I get the error: 'There was an error loading types from assembly C:\inetpub\wwwroot\project\Bin\AjaxControlToolkit.dll Could not load file or assembly 'System.Web.Extensions. Version=

Error: ASP.NET Ajax client-side framework failed to load.

Getting some errors after implementing the calendar control.  Error: ASP.NET Ajax client-side framework failed to load.  Here are some screenshots of the relevant info:   Here's the scenario...  I compile code locally, view the pages in a browser locally, and it all works fine.  Another developer sits down at my machine, logs in with AD account (which create a local profile for his account on my machine), and gets these errors when viewing my locally compiled code.  He then compiles the same code on my machine again just for a test, but still gets the same errors.  Can anyone come up with any good reasons for this behavior?  I put a call into MS and they suggested creating a new profile for the other developer with the errors since this appeared to be profile specific.  Tried doing that with the same results.  Help!

Ajax Control Toolkit Error Creating Control

Error Creating Control - ToolkitScriptManager1Unknown server tag 'asp:ToolkitScriptManager'.Error Creating Control - ComboBox1Unknown server tag 'asp:ComboBox'.I encountered this error, very annoying becasue it would shut off design view rendering of ComboBoxes as well as entire parent containers like ListViews.  It took me a lot of efforts to hunt down the cause, which would seem very illogical if not weird.  So I am suspecting that it is just happening to me, but would appreciate if somebody could care to reproduce and see if it is actually a bug.Cause: HtmlHead title tag has textFix: Delete text in HtmlHead title tagSteps to reproduce and verify error:1.
